Understanding the role of the immune system in aging and chronic metabolic disease.

Lab focus

The immune system is a remarkable orchestrator in the body.  While it is critical in fighting off infectious pathogens, it also has the capacity to communicate with other tissues and regulate fundamental physiology.  The Winer lab is interested in understanding how the immune system influences physiological processes and contributes to chronic disease.   Two focuses of the lab will be to understand how the immune system contributes to insulin resistance and diabetes as a model chronic disease, and also how immunology impacts the aging process itself. 

During obesity and age related insulin resistance, chronic low grade inflammation is emerging as an important factor driving the disease process. The Winer lab has made fundamental findings in understanding how the immune system, including the adaptive immune system, contributes to low grade inflammation in metabolic tissues, such as the liver and fat, as well as in the intestines during diet induced obesity. The lab also investigates how metabolic changes inside immune cells are influenced by external hormones to control immune cell function during homeostasis and disease. Thus, the focus of the lab falls into the scope of the growing field of “immunometabolism”.  The goal is to use this information to develop new translational diagnostics and therapeutics, including immune therapies and vaccines.

Why it matters

The worldwide levels of obese and aged populations are at their highest amounts in human history. Obesity and aging predispose to a wide variety of chronic health issues, including insulin resistance and diabetes, which is associated with significant morbidity, mortality, and economic burden on the healthcare system. The immune system is altered during obesity and aging, and may represent a crucial common link to better understand complications of these “conditions” and to devise novel immunotherapies for them.

The immune system likely plays a role in nearly every disease, even ones previously thought to be unrelated to immunology. It is only through the study of immunology that new immunotherapies, including vaccination approaches, be available for chronic diseases and processes associated with aging or obesity.

Dan Winer, MD

Dr. Dan Winer received an Honor’s BSc in immunology from the University of Toronto, followed by an MD from the University of Ottawa in 2002. He then completed residency training in Anatomical Pathology at the University of Toronto in 2007. Subsequently, Dr. Winer did a three-year post doc in immunology at Stanford University in the laboratory of Stanford Blood Center director, Dr. Edgar Engleman. During this time, Dr. Winer, collaborating with his twin brother Dr. S. Winer at the University of Toronto, spearheaded a new initiative which identified the adaptive immune system as an important player in the control of metabolic diseases such as obesity related insulin resistance and type 2 diabetes. Dr. D. Winer returned to Canada in 2010 and became an Assistant Professor at the University of Toronto in 2011, where he ran an obesity and inflammation research lab associated with the Toronto General Research Institute (TGHRI), before joining the Buck Institute.

Dr. D. Winer is the recipient of several awards including the Hubert Wolfe Award in Endocrine Pathology, the Benjamin Castleman Award for human pathology research (sponsored by the United States and Canadian Academy of Pathology and the Massachusetts General Hospital), the Amgen early investigator award (Endocrine Society), and the Canada Research Chair in Immunometabolism.

  • Juliet Bartleson, PhD  Postdoctoral Research Fellow

    Juliet received her bachelor’s degree in molecular and cell biology and physiology from Sonoma State University in Rohnert Park, California, in 2015. Her undergraduate research focused on a protein involved in proximal T cell receptor signaling, instilling in her a fascination with how immune cells function. She then joined the Immunology PhD program at Washington University in St. Louis, where she worked in the laboratory of Dr. Paul Allen researching how tonic T cell receptor signaling influences CD4+ T cell function. After receiving her PhD in 2020, she joined the laboratories of Drs. David Furman and Daniel Winer at the Buck Institute to integrate her passion for immunology and desire to focus on human-related health in aging.

  • Rohini Emani, PhD  Postdoctoral Research Fellow

    Rohini received her PhD in mucosal Immunology from University of Turku, Finland. Research focus on role of dietary fibers in modulating microbial and immune changes in cause of T1D in NOD mice. After her PhD she joined as a postdoc at Boston Children’s Hospital, Harvard Medical School in 2017 her research focus on developing various humanized mice models for translational biology and study human immune modulations of IBD in humanized mice models upon treatment with novel therapeutics. Rohini expertise in mucosal immunology and T cell biology. Further Rohini will be focusing on understanding the role of immune cells in Blood Brain Barrier access in AD and Obesity research in aging.
